Abstract
The present invention discloses the machining process and cutter for expanding and extruding back taper tooth of synchronizer tooth cover. The cutter is elastic ring one comprising several assembled blades and has outer notched edges and central through hole. After the cutter is stretched into the tooth cover and conic expanding core is stretched into the through hole, the driver drives the expanding core into the through hole further and the cutter is expanded to make the edges extrude the inner wall of the workpiece to form corresponding tooth groove with metal spring inside the notch. The present invention can form standard tooth groove without burr, and the tooth cover can well mesh with gear.
Description
Technical field
The present invention relates to a kind of synchronizer tooth cover back taper tooth method for expanding and extruding process method and cutter thereof.
Background technology
With working gear slip phenomenon takes place often for solving automobile synchronizer tooth cover, the engaging tooth of automobile synchronizer tooth cover generally is designed to the back taper tooth.Promptly be that the key two ends that tooth cover inwall is provided with the involute spline that is parallel shape are the pawl shape, the front portion is a crown, and the rear portion is the tooth tail, middle is that tooth is takeed on, the tooth tail progressively increases to tooth shoulder breadth degree, and tooth is takeed on the crown width and progressively reduced until becoming point, and the tooth shoulder is identical with middle spline width.Because the width of tooth tail is more smaller than adjacent spline, therefore, permissible accuracy is higher relatively.Traditional method is the method processing of rolling, and promptly cutter is rotating and reverse repeatedly at workpiece diameter.But because time of rotating and strength in case take place unevenly, will form engaging tooth and cooperate badly, and tooth top and tooth root easily form burr, influences result of use.
Summary of the invention
For solving as above problem, the invention provides a kind of synchronizer tooth cover back taper tooth method for expanding and extruding process method and cutter thereof.
The present invention is a kind of synchronizer tooth cover back taper tooth method for expanding and extruding process method, its cutter is spliced into the elastic ring state by several blades, the edge of a knife that is the teeth groove shape is in the outside, a teeth groove is a blade, center cutter is the through hole of the cutter hub ring bag of each blade, cutter is stretched into ring tooth cover inwall, to there be the stamen front portion of rising of certain taper to stretch into through hole, when the power set transferring power is given the stamen that rises, make the stamen that rises further clamp-on through hole, cutter progressively is radial expansion, makes edge of a knife extruding workpiece inwall, forms corresponding teeth groove.
Blade is spliced into the mode of elastic stage for being to be provided with spring groove on cutter hub, and the metal spring hoop is in spring groove.
For implementing the employed cutter of said method is several blade circular array states, and the edge of a knife that is the teeth groove shape is in the outside, and center cutter is the through hole of the cutter hub ring bag of each blade, and cutter hub is provided with spring groove, and metal spring is in spring groove.
The present invention is a blade with a teeth groove, and make the edge of a knife be the teeth groove shape, blade is formed the cyclic spring splicing with the metal spring hoop, be convenient to be the stamen crowded cutter hub through hole that rises under the effect of power that rises of certain taper, make it be radial expansion, edge of a knife extruding tooth cover inwall forms teeth groove, because this method is stressed evenly, the method that must not resemble rolling rotates and reverse repeatedly, therefore formed teeth groove standard, no burr.Tooth cover and gear engagement states are good during use.

The specific embodiment
Shown in Fig. 1 and 2, a kind of synchronizer tooth cover back taper tooth method for expanding and extruding process method of the present invention, its cutter is by ring of 30 blades, each blade is made up of the edge of a knife 1 and cutter hub 2, the edge of a knife 1 is on the top of cutter hub 2 one ends, the centre position on cutter hub 2 tops is provided with a spring groove 6, and the metal spring hoop is in spring groove 6.Center cutter is a through hole 3.Hydraulic press control chuck, chuck inserts and puts system tooth cover 5, cutter is placed on tooth and overlaps in 5 inwalls, make the edge of a knife 1 be close to tooth and overlap 5 inwalls, will be truncated cone-shaped has certain taper stamen 4 front portions of rising to stretch into through hole, squeezes the top stamen 4 that rises with fluid press power then, make the stamen 4 that rises constantly get into through hole 3, make cutter progressively be radial expansion, make the edge of a knife 1 extruding workpiece 5 inwalls, form corresponding teeth groove.
